Using our renowned Racelight geometry, the kinesis 4S offers a true race geometry but with the ability to fit full length mudguards & a pannier rack. The Kinesis 4S is for the rider looking for a Winter bike that will handle like their Summer race bike, or a Winter bike that they can race through the Summer. A true four seasons bike.

Features: The Kinesis 4S is the natural evolution of our very first Winter training frames, however the Kinesis 4S should not be consigned to Winter riding only. We have put everything we have learned during the last 17 years of geometry, & alloy frame design & manufacture into the Kinesis 4S. Whilst other manufacturers focus has been on carbon, we believe that by putting the same development into alloy tubing, we have created a frame that rivals carbon in many ways, & hands down beats it on price. Damian Mason of Kinesis UK said ‘ Kinesis are the only frame manufacturer to use Super Plastic Forming (SPF) on their alloy frames. Most manufacturers use Hydroformed tubes, but with SPF we can create lighter tubes & more intricate shapes that will build into a lighter & stiffer frameset.’ We have combined our SPF Kinesium aluminium frame with our renowned Tracer Disc Thru Axle full carbon monocoque fork. The Tracer Disc’s square crown provides the perfect space for mounting our Kinesis Fend Off full length mudguards. The Tracer Disc has great tyre clearance, internal routing, mudguard compatibility, discreet Shimano flat mount fitting, all in a lightweight package. As with our premium titanium Kinesis GTD frameset, we have partnered with GW engineering & we are supplying the Kinesis 4S with their patented ‘ Switch Lever’ hollow Thru Axles with a removeable lever. The Kinesis 4S uses adaptable cable ports which allow you to build your frame with exactly the right cable routing for whether you are running Di 2 or mechanical gearing with either a 1x or 2x set up. The frame has twin bottle mounts on all sizes along with mudguard & rack mounts.

For 2020 the Aithein is back to reclaim its place as the fastest bike in the Kinesis lineup. Our premium aluminium race frame is faster, more comfortable & more fun than ever before. Whether its racing the local crit or winning the sprint for the sign, the Aithein is the bike to get you there faster. Using advanced aluminium construction techniques, we’ve created a frame that truly questions the need for a carbon bike. Thanks to the advanced manufacturing technique called Superplastic Forming (SPF), we’ve minimised weight whilst maximising stiffness & strength where you need it. The result is a high-performance frame that excels in transferring rider energy into forward momentum. The new Aithein features 28mm tyre clearance for speed & grip, allowing you to ride at full speed on every road surface. To complement the frame we chose the excellent Futura Road fork from Columbus, known for its impeccable ride quality, & unmatched vibration damping. Flat mount brake attachment & Industry standard 12mm thru axles are used on the disc brake model with GW’s excellent switch lever for a clean looking & dependable set up. More traditional riders will be pleased to know that the Aithein frame is also available in caliper option. No matter how you choose to ride, if you choose to ride fast, choose to ride Aithein!
